I have seen this happen on a few different types of machines running
System V Release 2.  I think it is a bug related to execing a file which
has pending delayed-write blocks in the cache.  I have only seen it
happen when the program is invoked immediately after it is written, as
in the shell command "make foo && foo".

I have seen it happen on the Unix PC when compiling gcc, because of the
way it compiles a program like "genoutput" and then runs it to generate
some more code.
